DUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 595,528, dated December 14, 1897.

Appiicmon med April 9, 1897. serial No. 631,411. (No model.)

To all whom it may concern:

Be it known thatV I, JAMES Gr. DELANEY, of New York city, in the county and State of New York, have invented a new and Improved Dumping Apparatus, of which the following is a full, clear, and exact description.

The'purpose of this invention is to provide an improved dumping apparatus by which a load-receptacle or bucket may be raised, low-v ered, or conveyed and, when desired, dumped.

The invention is susceptible of use in various connections, such astransfer or cable systems, but in the drawings it is shown applied to a derrick as one application of the invention.

The invention will be fully described hereinafter and its scope defined inthe claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 isa side elevation of the invention in use. Fig. 2 is a vertical section taken through the fall-block. Fig. 3 is an end View of the fall-block and skip or load-receptacle,

and Fig. 4 is a detail section taken throughthe pulley of the fall-block.

According to the specic device given in the drawings as an illustration, the boom 5 of the derrick has a block 6 swiveled thereon and carrying a cable 7 ,which runs in the usual manner around the sheave or pulley 8 of the fall-block. Interposed between sections of and forming part of the cable 7 is a chain 9, the links of which are wider than the thickness of the remaining portion of the cable, so that portions of the links will'proj'ect beyond the sides of the sheave 8 of the fallblock. This chain 9 may, if desired, be substituted by any device which increases -the size of the cable at a certain point. Itis not essential that the spe'ciiic chain be used, as will more fully appear hereinafter.

The fall-block is shown as having two vertically extending frame plates- 10, rigidly joined to veach other at their upper and lower ends by transverse pins 14% Intermediate portions l1 of the frame-plates 10 are projected outwardly and fixedly carry a transverse pin or shaft 12. Respectivelyengaging the frame-plates 10 are the cheek-pieces 13 of the fall-block, which are joined to each other at their outeredges by means of transverse pins 14. The sheave 8 of the fall-block is mounted loosely on the center of the shaft 12. Loosely mounted on the shaft 12, and one oneach side of the sheave 8, are the two winding-drums 15, the inner ends of' each of which respectively project through openings in the cheek-pieces 13 and respectively rigidly carry annular plates or disks 16, which lie adjacent to the respective sides of the sheave 8 and preferably have a diameter greater than that of the sheave, so that the peripheries of the plates or disks 16 will project beyond the periphery of the sheave. The

wardly beyond the cheek-pieces 13 and are embraced by the outwardly-extended portions 11 of the frame-plates 10.r Fixed to each drum 15 is astaple 17, to which the chains 18 are respectively connected. The chains 18 are also connected with the rear end o f the load-receptacle, skip, or bucket 19. The loadrecepta-cle or bucket 19 is provided at its center with a cross-bar 20, with which a hook 21 connects, the hook being carried by the pin 14a, which passes transversely between the frame-plates 10 at the lower ends thereof.

The cable 7 passes around the sheave 8. The load in the receptacle 19 so disposes the receptacle thaty the chains 18 or equivalent carrying devices are held taut in the positions shown by full lines in Figs. 1 and 3. As the cable 7 runs around the sheave 8 and when the chain 9 engages the sheave the links of the chain 9, being wider than the cable 7 is thick, will project laterally to' engagement with the notches 16a in the inner faces of the disks or plates 16. This will cause the disks or plates 16 to be revolved and the chains 18 will be wound on the drums. This will draw up one end of the bucket or load-receptacle 19 and the same will be dumped, as the dotted lines in Fig. 1 show.

It will be understood that the particulardevices shown are given for the purpose of illustrating one specific embodiment of my invention and are not the measure of the general invention hereinafter deiined in the claims, to which latter the language measuring the scope of the invention is properly relegated. Thus generically the drums are devices mounted to be turned, and the drums or ap- `main portions of the drums 15 project out- IOO purtenant part or parts thereof are directly engaged to dump the load by the chain-links or any other suitable trips in the path of the engaging appurtenant parts of the drums, the rotative movement of said trips and the drums or theirappurtenant trip-en gaging parts serving directly to effect the turning movement.

It will be seen that this dumping of the receptacle takes place no matter in which direction the chain 9 moves relatively to the fall-block or similar device embodying my invention. It will also be seen that the chain 9 may be substituted by any device which will engage with the plates or disks 16. The connection which causes the drums 15 to wind the chains 18 is not with the sheave 8, but is directly with the element which turns the drum. The sheave S performs no function in the dumping operation. It is merely useful for carrying the cable, and any other device which can serve such function may be used in place of the sheave. The operation of the drums 15 is independent of the operation of the sheave, since, if desired, one cable may be run around the sheave to support the fall-block and a second and separate means provided to transmit movement to the drums.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a frame, of a winding-drum mounted therein, a sheave mounted adjacent to the winding-drum, the sheave being capable of carrying a cable and being freely movable in each direction independently of the winding-drum, and the windingdrum being capable of connection directly with the cable, whereby it is operated by the cable, substantially as described.

2. The combination with a frame, of a Winding-drum mounted on the frame, and a sheave mounted on the frame adjacent to the winding-drum and capable of turning freely in each direction independently of the windingdrum, the winding-drum havinga member in connection therewith, such member being located adjacent to the sheave and being capable of locking with the element that engages the sheave, whereby motion is transmitted directly from said element to the windingdrum irrespective of the operation of the sheave, substantially as described.

3. The combination with a frame, of a winding-drum mounted thereon, a plate or disk fixed to the winding drum, and a sheave mounted to turn freely in both directions independently of the winding-drum, the sheave being located adjacent to coact with the means by which the frame is supported, the plate or disk being capable of engaging directly with an element having movement relative to the frame,whereby the winding-drum is operated directly from said relatively-moving element irrespective of the movement of the sheave, substantially as described.

4. The combination with a frame, of a shaft mounted therein, a winding-drum mounted to turn freely on the shaft, a sheave mounted on the shaft, and a plate or disk in rigid connection with the winding-drum and located adjacent to the sheave, the sheave and wi nd-y ing-drum being each operative independently of each other,substantially as described.

5. The combination with a frame, of a shaft mounted therein, a winding apparatus carried by the shaft, and means also carried by the shaft for engaging an clement by which the frame may be supported, the winding apparatus and said means being independently operative, and the winding apparatus being capable of directly engaging a part having movement relative to the frame, whereby to operate the winding apparatus from said part irrespective of said means, substantially as described.

6. The combination of two frame-plates having rigid connection with each other, and each having an outwardly-extending intermediate portion, a cheek-piece adjacent to each frame-plate, a shaft extending transversely between the outwardly-extendin g portions of the frame-plates, a sheave mounted loosely on the shaft, two drums mounted loosely on the shafts and respectively on the sides of the sheave, the drums respectively extending into the outwardly-extending portions of the frame-plates, and a plate or disk attached to the inner portion of each drum and respectively lying adjacent to the sides of the sheave and inside of the cheek-pieces, substantially as described.

'7. The combination with a frame, of a shaft mounted therein, two cheek-pieces carried by the frame and through which the shaft eX- tends, a sheave mounted on the shaft between the cheek-pieces, two drums mounted on the shaft and respectively on the sides of the sheave, and a plate or disk carried by the inner end of each drum and respectively adjacent to the sides of the sheave, substantially as described.

8.
